The infinite connundrum.
I don't normally do this ('this' being book recommendations), but I've just finished reading Discovery Road. Its the diary of a couple of British lads who decided over a beer one day to cycle across 3 continents in a year - Australia, Africa and South America. Totally unsupported, with only what they can carry on their bikes.
Its funny and inspirational in equal measure.
And now, I go to drink beer and be useless all afternoon. Such is my lot in life
